i remember being surprised when i heard bellew was ahead.
his game that night was basically to try and time usyk with a right hand, but he didn't do much else. it was enough to keep usyk wary for a while, but eventually he got bellew's timing down and started touching him at will. that KO was awesome.
it's a recurring theme in usyk's fights. he looks cautious and timid early, but by the mid rounds has his man figured out and puts the pressure on.
